If anyone is looking for a good low speed fan for a reasonable price this is it, and the AC cord has an on and off switch. I put 4 self stick rubber pads on the bottom and it's drawing air up out of the 8801. I also Velcro'd one to the side of my Sunfire amp
Looks like I bought the last 3 of them but I'm sure they'll restock them.
So if you're only using one top mounted fan - that's the place to put it.
I bought two CoolerGuys fans that sit atop the AV8801 and are triggered by a thermostat that I have set to turn them on at 85 degrees. Works pretty well.
